我想创建一个应用程序来跟踪安装了我的应用程序的用户，因此我有以下用于跟踪的代码，该代码运行良好，但只会返回CITY NAME。但是我需要像街名，城市之类的明智的完整细节。
public class GetCurrentLocation extends Activity
implements OnClickListener {
private LocationManager locationMangaer = null;
private LocationListener locationListener = null;
private Button btnGetLocation = null;
private EditText editLocation = null;
private ProgressBar pb = null;
private static final String TAG = "Debug";
private Boolean flag = false;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//if you want to lock screen for always Portrait mode
setRequestedOrientation(ActivityInfo
.SCREEN_ORIENTATION_PORTRAIT);
pb = (ProgressBar) findViewById(R.id.progressBar1);
pb.setVisibility(View.INVISIBLE);
editLocation = (EditText) findViewById(R.id.editTextLocation);
btnGetLocation = (Button) findViewById(R.id.btnLocation);
btnGetLocation.setOnClickListener(this);
locationMangaer = (LocationManager)
getSystemService(Context.LOCATION_SERVICE);
}
@Override
public void onClick(View v) {
flag = displayGpsStatus();
if (flag) {
Log.v(TAG, "onClick");
editLocation.setText("Please!! move your device to" +
" see the changes in coordinates." + "\nWait..");
pb.setVisibility(View.VISIBLE);
locationListener = new MyLocationListener();
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions

return;
}
locationMangaer.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5000, 10, locationListener);
} else {
alertbox("Gps Status!!", "Your GPS is: OFF");
}
}
/*----Method to Check GPS is enable or disable ----- */
private Boolean displayGpsStatus() {
ContentResolver contentResolver = getBaseContext()
.getContentResolver();
boolean gpsStatus = Settings.Secure
.isLocationProviderEnabled(contentResolver,
LocationManager.GPS_PROVIDER);
if (gpsStatus) {
return true;
} else {
return false;
}
}
/*----------Method to create an AlertBox ------------- */
protected void alertbox(String title, String mymessage) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Your Device's GPS is Disable")
.setCancelable(false)
.setTitle("** Gps Status **")

Intent myIntent = new Intent(
Settings.ACTION_SECURITY_SETTINGS);
startActivity(myIntent);
dialog.cancel();
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// cancel the dialog box
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
}
/*----------Listener class to get coordinates ------------- */
private class MyLocationListener implements LocationListener {
@Override
public void onLocationChanged(Location loc) {
editLocation.setText("");
pb.setVisibility(View.INVISIBLE);
Toast.makeText(getBaseContext(),"Location changed : Lat: " +
loc.getLatitude()+ " Lng: " + loc.getLongitude(),
Toast.LENGTH_SHORT).show();
String longitude = "Longitude: " +loc.getLongitude();
Log.v(TAG, longitude);
String latitude = "Latitude: " +loc.getLatitude();
Log.v(TAG, latitude);
/*----------to get City-Name from coordinates ------------- */
String cityName=null;
Geocoder gcd = new Geocoder(getBaseContext(),
Locale.getDefault());
List<Address> addresses;
try {

.getLongitude(), 1);
if (addresses.size() > 0)
System.out.println(addresses.get(0).getLocality());
cityName=addresses.get(0).getLocality();
} catch (IOException e) {
e.printStackTrace();
}
String s = longitude+"\n"+latitude +
"\n\nMy Currrent City is: "+cityName;
editLocation.setText(s);
}
@Override

尝试这个 ：
public void setCurrentLocation() {
if (UtilityMethods.isGPSEnabled(mContext)) {
if (Build.VERSION.SDK_INT >= 23 &&
ContextCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &&
ContextCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(LOCATION_PERMS, LOCATION_REQUEST);
// return;
} else {
getCurrentAddress();
}
} else {
alertbox("Gps Status", "Your Device's GPS is Disable", mContext);
}
}
使用LocationManager
public void getCurrentAddress() {
// Get the location manager
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if (locationManager != null) {
try {
if (Build.VERSION.SDK_INT >= 23 && checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// public void requestPermissions(@NonNull String[] permissions, int requestCode)
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for Activity#requestPermissions for more details.
return;
}
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
} catch (Exception ex) {
Log.i("msg", "fail to request location update, ignore", ex);
}
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
}
Geocoder gcd = new Geocoder(getBaseContext(),
Locale.getDefault());
List<Address> addresses;
try {
addresses = gcd.getFromLocation(location.getLatitude(),
location.getLongitude(), 1);
if (addresses.size() > 0) {
String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
String locality = addresses.get(0).getLocality();
String subLocality = addresses.get(0).getSubLocality();
String state = addresses.get(0).getAdminArea();
String country = addresses.get(0).getCountryName();
String postalCode = addresses.get(0).getPostalCode();
String knownName = addresses.get(0).getFeatureName();
if (subLocality != null) {
currentLocation = locality + "," + subLocality;
} else {
currentLocation = locality;
}
current_locality = locality;
}
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(HomeActivity.this, Constants.ToastConstatnts.ERROR_FETCHING_LOCATION, Toast.LENGTH_SHORT).show();
}
}
